Hi Guys

Looking for input from you people with more experience on boards than me 😉.
Been kite foiling for 4 yrs
Getting into SUP foiling.
Already have a home made
7'6"
But want a smaller board for winter and bigger waves.
48yrs young
6' 
wieght 93kgs
I have just drawn up 2 boards on  Aku.
I just want your opinion o  which one to build.
Thanks for your help.
